Patented Apr. 2, 1940 PATENT OFFICE WOVEN ELASTIC FABRIC John V. Moore, Pawtucket, R. I., assignor to Moore Fabric Company, Pawtucket, R. I., a corporation of Rhode Island Application July 10, 1939, Serial No. 283,543

1 Claim.

This invention relates to a woven elastic fabric particularly adapted for use as a gore in a boot or shoe.

It is desirable in such products that the selvage portions of the fabric be more strongly contractive than the middle portion, and it has been proposed to attain this result by increasing either the size or the number of the rubber threads adjacent the selvages. While such an arrangement will give increased strength, it also definitely changes the appearance of the fabric adjacent the selvages, whereas a uniform surface effect is usually desired.

It is the general object of my present invention to improve the construction above described by securing the increased contractive power by employing selvage rubber threads of the same size as the regular threads but of such composition that they have substantially greater strength. These stronger selvage threads are spaced uniformly with the regular threads, so that a desired uniformity of surface effect may be attained.

My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed. out in the appended claim.

A preferred form of the invention is shown in the drawing, in which:

Fig. 1 is a plan View of a portion of woven elastic fabric embodying my improvements; and

Fig. 2 is a sectional view of the fabric, taken along the line 2-2 in Fig. 1.

Referring to the drawing, I have shown a woven elastic fabric F having rubber warp threads Hi and H which are all of the same size and cross section and which are all uniformly spaced across the fabric.

The rubber threads I and the rubber threads I I are formed, however, of different kinds, grades or mixtures of rubber, so that the selvage threads ll, while of the same size and cross section. are nevertheless substantially stronger and of substantially greater contractive force per thread than the threads l0, which may be termed the regular rubber warp threads.

The fabric is commonly woven with non-elastic weft and with additional non-elastic warps, and the weave may be of any desired construction, so long as lengthwise expansion and contraction of the web is permitted. For shoe gore purposes, it is desirable that the outer face I2 of the fabric should show only non-elastic weft and non-elastic warps, while the rubber warp threads are well concealed below the face l2 of the fabric.

In a fabric constructed and woven as above described, extreme uniformity of surface appearance from edge to edge of the fabric is attained,

while the contractive force of that part of the web adjacent the selvage, when stretched, is very substantially greater than the force of a similar width of the fabric in its middle or intermediate portion.

Having thus described my invention and the advantages thereof, I do not wish to be limited 2 equally elongated.

JOHN V. MOORE.
